I have the following formula in a couple of cells and want to use code instead.

='P:\NAP Office\VT-31 Classes\[VT31 FY 04-37.xls]Tracker'!C9

The formula refers to another workbook on another drive. The reason I want
to use code instead is that I want to be able to change the reference at the
04-37 portion of the formula through an input box to other numbers in the
same general format ie. 04-##. Any thoughts?
